对33例肉眼可见肿瘤累及的肝脏进行尸检后，研究了肝转移瘤超声晕征的起源。对于20个病变的结果进行了详细的比较，从高分辨率7.5和10 MHz的超声，微血管造影和组织学。组织学研究主要集中在肿瘤周围及其与邻近肝实质的关系。特别是，肿瘤浸润的类型，存在或不存在瘤周纤维化和肝细胞压缩的程度进行了评估。除2例外，所有病例的晕圈均为瘤外，由瘤周肝细胞压迫引起。在其余2例病例中，晕圈是肿瘤性的，由不规则纤维化或血管化引起。
The origin of the sonographic halo sign in liver metastases was studied after autopsy in 33 [human] livers with macroscopic tumoral involvement. For 20 lesions a detailed comparison of findings from high-resolution 7.5-and 10-MHz sonography, microangiography and histology was carried out. Histologic study focused on the tumor periphery and its relationship to the adjacent liver parenchyma. In particular, the type of tumor infiltration, the presence or absence of peritumoral fibrosis and the degree of liver cell compression were assessed. In all but 2 cases the halo was extratumoral and was caused by peritumoral liver cell compression. In the remaining 2 cases the halo was tumoral and was caused by irregular fibrosis or vascularization.
